I would be fascinated if you managed to pull of a stereo. I mean the origin of the projection for any given direction needs to be distributed sort of around a ring:
If you imagine that each unique color on the image above is unique direction for left and right eye, you can sort of see how the origins of the cameras would have to be shifted. I have no clue how I’d do that with rasterization, using just scene captures. So I haven’t even tried, because I assumed the stereo just would not work.
